The OSSEC Effect

Many years ago, after I had been using OSSEC in an enterprise setting for a few months, I noticed an interesting phenomenon. Administrators, many of whom I had forwarded “was this you?” alerts to, were now coming to me to rat on themselves.

I would be working away in my cubicle when someone would come up behind me. It went something like this:

“Hey, Mike. Just wanted to let you know what you’ll be seeing me <insert action here> in the logs. No cause for concern.”

“Thanks for the heads up,” I would reply.

The administrators knew they were being monitored, but didn’t exactly know the full details of the monitoring. They naturally assumed I would see what they were up to. In many cases I wouldn’t have known.

The vast majority of these folks were honest to begin with, but I can’t help think it assisted them in following process and being just a bit more transparent with what they were doing. Maybe it even¬†dissuaded¬†someone who was on the fence from doing something vindictive.

After seeing this in other environments, I think it deserves a term. At the risk of coining a term for something that has already been identified, I hereby declare this the “OSSEC Effect.” The definition (which could use some refinement) is as follows:

OSSEC Effect: The alteration of a computer user’s behavior when they know their actions are being monitored, but do not realize or understand the extent of the monitoring. Users will, without¬†provocation, volunteer information they believe could be seen as questionable, whether the monitoring system would have known about it or not.
